Julian Britnell, sales manager at Hart Doors Systems, manufacturers of the Speedor range, says Speedors offer exceptional benefits to end-users. “The commonly seen open door is a source of heat loss and increased energy costs. Speedor’s automatic action greatly reduces the time a door is open, improving shop floor environment and cutting heating bills too. Further, an important aspect of this installation is it also cuts down the chance of dust and other airborne debris from accessing a building where cleanliness is vital,” says Julian Britnell.
